Designing PSU

1 post / 0 new

Hi,

 

I designed a PSU. In my design, the outputs are   Vo =36 V and Io=1,4 amps. I used PI Expert and i choose TOP266, and i select openframe instead of adapter selection. However, after I ordered the transformer, i recognize my mistake:

 

P = 36 x 1,4 =  50,4 W 

 

For TOP266,

max.power of adapter selection is : 40 W 

max.power of open frame selection is : 86 W  

 

For TOP266,

max.power of adapter selection is : 55 W 

max.power of open frame selection is : 103 W  

 

So can i use TOP267 intead of TOP266 in the same desing according to TOP266?
